S8V Circuit Breakers

S8V circuit breakers are a specialized category of high-performance miniature circuit breakers (MCBs) and molded case circuit breakers (MCCBs) designed for industrial automation and electrical distribution systems. These devices are engineered to provide reliable overcurrent and short-circuit protection in demanding environments, with ratings typically ranging from 0.5A to 63A for MCBs and up to 1600A for MCCBs. Key technical specifications include breaking capacities up to 25kA at 415V AC, trip curves B, C, D, and K for selective coordination, and voltage ratings up to 690V AC. The S8V series features compact modular designs with 1P, 2P, 3P, and 4P configurations, DIN rail mounting for easy integration into control panels, and optional auxiliary contacts, shunt trips, and undervoltage releases for enhanced functionality. These breakers comply with international standards such as IEC 60947-2 and UL 489, ensuring global acceptance and safety.

S8V circuit breakers are deployed across a wide range of industrial sectors, including manufacturing plants, process automation, renewable energy systems, and commercial building infrastructure. They are commonly installed in main distribution boards (MDBs), sub-distribution boards (SDBs), motor control centers (MCCs), and programmable logic controller (PLC) cabinets. Typical applications include protection of motors, transformers, lighting circuits, and power supplies in automated production lines, conveyor systems, and HVAC installations. Their robust design makes them suitable for harsh environments with high ambient temperatures, vibration, and dust, often requiring IP20 or higher enclosure ratings.

The S8V category encompasses several subcategories and key article codes that define the product range. Main subcategories include S8V-MCB for miniature circuit breakers (e.g., S8V-MCB-10A-3P-C), S8V-MCCB for molded case circuit breakers (e.g., S8V-MCCB-100A-3P-25kA), and S8V-RCBO for residual current circuit breakers with overcurrent protection (e.g., S8V-RCBO-30mA-16A-2P). Article codes typically follow a structured format: S8V-[Type]-[Current Rating]-[Poles]-[Trip Curve]-[Breaking Capacity], where Type indicates MCB, MCCB, or RCBO, and optional suffixes denote accessories like auxiliary contacts (AUX) or shunt trips (ST). For example, S8V-MCB-20A-1P-C-10kA represents a 20A, single-pole, C-curve MCB with 10kA breaking capacity.
